allergyWhat is Allergy?

An allergy is an exaggerated response of our organism, when in contact with certain substances from outside. Substances capable of causing an allergic reaction are called allergens or simply allergens.

How do you get?

The immune response is of great importance but sometimes causes serious problems:

In organ transplants (kidney, heart, lung …) our immune system identifies the new organ as foreign and try to put in place to combat it, if not the rejection medications are given to reduce this response (called immunosuppressants).

Sometimes confuses the immune system components of our body with foreign elements and starts a reaction against them leading to the autoimmune diseases (many rheumatic conditions are the origin).

Sometimes it produces an immune response in the presence of harmless substances to the body, which are usually tolerated by it. This overreaction is called allergy and the substances are allergens that trigger. The potential allergens are very numerous and may contact us through various means:

The air we breathe: plant pollens, house dust, fungi, animal hair … Food: fish, eggs, nuts, … Drugs: penicillin, aspirin, … Insect stings, bites, … Skin contact: cosmetics, industrial products …
